Abstract
The attenuation of Rayleigh surface waves by one‐ and two‐dimensional rough surfaces is investigated on duraluminum and titanium samples. The root‐mean‐square deviation of the surface from flatness h (8.5<hh/λR≪1. The excitation frequencies of the transmitter vary from 2.2. to 10 MHz. Experimental results for one‐ and two‐dimensional rough surfaces are presented and discussed. A comparison with the theoretical calculations of Eguiluz and Maradudin [Phys. Rev. B 2 8, 728 (1983)] confirms the F5 dependence of the attenuation α as aq∥→0.This publication has 6 references indexed in Scilit:
